OpencontouR Mining Software

Opencontour is an open pit mining software company which supports mining corporations in discovering the true value of their assets. We are former mining engineers who understand the challenges miners face everyday. Opencontour helps take the guesswork out of mine planning decisions.


We created Opencontour from our own personal experiences with mining software programs that didn't meet our expectations. Opencontour helps ease the burden of difficult mine planning decisions by measuring cost-benefit scenarios for alternate mine designs and schedules. 

Opencontour Image - open pit planning, mine design, mine scheduling, heap leach stacking, recovery, cashflows, financial analysis

Opencontour consists of a Core Design program and tools for Open Pit Scheduling, Heap Leach Stacking, and Heap Leach Recovery optimization. 

Software capabilities

  • Iteration tools accelerate mine design and schedule plans

  • Compare current design plans to alternative options to measure financial impact

  • Mine schedule analysis by phase for pit and bench designs, truck fleet and load efficiency, stockpile logistics, haul routes, and dump locations 

  • Organizes heap leach stacking into discretized cells (blocks or panels) for metallurgical performance tracking and optimization refinement

  • Map and qualify dumping and heap leach pad arrangements to measure cost-benefits

  • Valuation tools include open pit equipment scheduling, metal extraction accountability and financial management.
